Is this a pH problem, or a Nitrogen problem, or a Broad Mite problem

[OneEyedWilly]

This is my 3rd DoSiDo grow, currently Vegn @ 62RH, 24’C, 18on6off, in soil and I noticed one of my girls looking sickly a few days ago and now see my other girls starting to not do well too.

So I brought out my pH meter and inserted it and waited 30sec for acclimation…It came to a rest of 7.0 (I know the recommendation is 6.2) and noticed that when I accidentally bumped the meter if momentarily went up to 8.5.

So I raced up to my local grow store and got some pH Down, and flushed the containers with 2x the volume of water.

My question is, as the thread title states, do the pictures substantiate my high pH diagnosis, as I have seen other similar posts where respondents thought it might be too high Nitrogen.

I also found the following link that looks EXACTLY like the pictures below:

Broad mites are tiny; they can be almost impossible to spot, and the symptoms may be similar to deficiency. Learn how to identify and get rid of them!

Thanks in advance.

Ps. The "WHITE" on the soil is NOT mold...It is Diatomaceous Earth...The absolutely BEST defense against bugs I've used so far but is an absolute nightmare to work with as it sticks to EVERYTHING.

Good morning my friend, hope you are well.
Just a quick question was she in flower?
It looks like some leaves are revegging.
Talk soon.

agree with bill. are you running autos or photos ? it looks like you've got a confused plant stuck between wanting to flower and reveg.

ph meter probes don't work very well. most ph their inputs and don't worry.

what else can you tell us about your grow ? there really isn't enough info to go on.

Thanks for your interest Bill284.

I started 10 clones 1 week before I reduced lighting from 18/6 to 12/12 (Dec 18th).

Only 1 of the clone attempts succeeded...The others rotted and died, so since it had been less than a week of 12/12, I started 4 new clones, just before Jan 01, which succeeded. So, to answer your question, there is a 66% chance that the one that is showing the most adverse growth had been exposed to 12/12 lighting for LESS THAN a week. Since just before Jan 01, they all experienced a minimum of 18hours of light a day, using USB powered LED grow lights, with no signs of bad growth...They grew from cutlings to 6 inch plants with 4-5 shoots.

On Feb 23, my tent that was being used to dry my previous grow in the dark became available for me to move the now 6 inch plants into the tent where I could use my larger LED lamp on them. I used a new potting soil than what I used before. It wasn't until about a week of growth in the tent that I first noticed the bad growth.

The strange thing is that one of the clones that I KNOW experienced a few days of 12/12 shows no bad growth yet.

I have read about revegging growth, but as I've stated they have been experiencing a minimum of 18 hours of light per day, and except for the clone fails and having to start new clones from mothers that had experienced less than a week of 12/12, everything (USB Lighting, growing outside the tent until previous growth had dried) was as I did on this grow cycle.

So it hard to believe that could they be experiencing/undergoing revegging since they've had over 18 hours of light for over 3 months before the problem first showed?

I've written a little more about my growth process in my reply to Bill284.

If you'd like more information, please let me know what else I can describe.

Did the mother plant flower? If she was given 12/12 for any more than 2-3 days then she was already beginning to cascade into flower so any cuts from her would also be trying to flower. If she got 2-3 days of 12/12 her hormones were moving toward flower and if you changed the light back to veg hours she would be stuck in between wanting to flower and revegging.

Ok so let's say there might have been a light issue.
Leave them under 24 hrs light and they will veg back just incase.
But that's not your question.
Soil generally self regulates the ph of your nutrients.
If your concerned set your nutrients ph to 6.3 prior to feeding.
But your girls look healthy and aren't showing signs of a ph issue.
Leaves are green and growing well, looking for light.
Not twisted or droopy.
Just curious though have you had any bugs?
Wondering why your asking about broad mites.
They are terrible.

[bluter]

you mention ph, what is your media and brand ? the word soil means nothing in indoor growing.

if you pulled those from a plant under 12/12 then switched to 18/6 they will definitely reveg and go through some bad looks while they get there.

i'm fairly certain you don't have broad mites or russets. the plants look like a healthy reveg for the most part.

I understand what you are implying...My apprehension is that they have been under 18+ hours of light for over 3 months...Shouldn't that have corrected by now?

Yeah a couple weeks usually does it.
So something is not right.
Run 24 hr light for few days and just get them all on the same page.

The reason I am worried about Broad Mites is that my plants look EXACTLY like those in the link I posted in the first posting. If there is an infestation, and it is early on in the infestation, then some of the leaves would still look healthy, wouldn't they?

Mites will eat your garden alive.
They damage the foliage and are fairly obvious.
The twisting is common on a revege.
But this leaf looks like it's rolled up in a ball?
Usually a bug does this.
Just check it.

It could be nothing, just have a look.

Is it a USB or did you mean LED light? If so what size light are you using. That isn't much growth for 3 months. Reveging is seen in new growth only. Low light would slow all progress. I clone from early flower all the time and this looks normal but the time is the concern.

 

[Sativa1970]

Low temp can also cause these same symptoms.

 

[bluter]

if it was broad mites or russets i'd expect more damage. don't wish for them as it will mean shutting the entire grow to deal with it. some growers take years to recover.

Yep, I misunderstood the mother’s situation. Typically a reveg would last 30ish days so that’s not it and can be eliminated

I use a 4 string USB LED light when cloning, then in the tent I have a more powerful LED light. This is my 3rd grow, and up until a week ago, I have not had any issues other than small harvests.

Yes...I agree about the power output of my tent light...I have been debating whether or not to upgrade to a more powerful light as my prior 2 growths using these same lights don't produce much.

I topped off the bad growth and looked, using my 120x magnifier) at both the top and bottom of the curled leaf.

I did NOT see any life. What I did see were tiny, perfectly circular, crystal clear (what looked like) "droplets". I also noticed that both sides were covered with clear trichome's (420_7), which would lend credibility to the revegging theory. The other thing to note was the the half of the leaves on the topped portion were wilted/soft/flabby and the other half were dry/crispy.

 

[SmokingWings]

As soon as I saw your photos I was able to see what you were seeing and why you thought about Broad Mites. Some of the photos of damage caused by Russet Mites can look similar.

Zero NOTICABLE bugs since applying the Diatomaceous Earth (Feb 23)

Were you able to apply the DE (Diatomaceous Earth) to the leaves themselves or just to the soil? Once the mite is in or on the leaf it is probably staying there.

Russet Mites seem to be easier to get under control and then eliminated. A sulfur sprays looks like a common treatment that works.

The Broad Mites are a different story. It looks like anything that controls that specie of Mite is also a systemic so it is absorbed by the plant and moves around whenever the plant is moving nutrients and sugars. If that is the case then the miticide ends up in the buds, including the sugar leaves, and stays there.
